    Simplify writing of output lines to Makefile
    
    Instead of writing everything to a temporary buffer, and then using
    fwrite() to have it fputc() one character at a time into the stdio
    buffer, just use fprintf() directly to save a copy and write in
    larger blocks.
    
    Testing on Solaris on makedepend's own source files showed a
    reduction in memcpy's from 4037 to 3108, and in _dowrite calls
    in stdio from 1173 to 168, but no change in actual write calls
    from stdio's buffer to the file.

    Remove unused variable whitespace
    
    Use of it was removed in commit 275c17136006f9d, but we kept setting
    it anyway.
    
    Resolves gcc 7.3 warning:
    main.c: In function ‘getnextline’:
    main.c:587:10: warning: variable ‘whitespace’ set but not used [-Wunused-but-set-variable]
      boolean whitespace = FALSE;
              ^~~~~~~~~~

    Fix bad indentation in ifparser.c

    ifparser.c:302:2: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘else’
      break;
      ^~~~~

commit 13385d8add69156805f824cedcdad2986a23662d

    Quote colons in filenames/paths
    
    Makefile doesn't like colons in filenames/paths so they must
    be quoted in the output. Otherwise makedepend doesn't work with
    full paths that contain a colon.
    
    V2: Use quoted filename when measuring name length
